Induction generators for precise industrial process heat

Induction generators for precise and demand-based heating

Induction heating systems enable tools and workpieces to be heated precisely, quickly and without contact. The induction generator and inductor work together as a coordinated system: The generator produces high-frequency electrical power and supplies it to the connected inductor. The inductor generates an alternating magnetic field that induces heat directly in the electrically conductive workpiece or tool. This means energy is delivered precisely where it is needed in the process.

With the Small Heating System SHS and the Modular Heating System MHS, Kendrion offers two generator solutions for different heating requirements. The compact SHS is designed for individual heating applications, such as sealing tools and rollers in packaging machines, as well as food and beverage applications. The MHS is ideal for more complex processes with multiple independently controlled heating zones, such as roller and cylinder heating in textile, printing and paper processing.

The key to efficient and reproducible heating is the correct design of the overall system. Kendrion matches the generator and inductor to the specific application, taking into account factors such as material, geometry, target temperature, cycle time and installation conditions. The result is an application-specific heating solution that can be integrated into existing machines and systems.

Small Heating System SHS – compact for up to 2 kW

The Small Heating System (SHS) is a compact solution for individual heating tasks with low power requirements. The generator operates on 230 V single-phase power and provides an adjustable output power ranging from 0 to 2 kW.
An integrated PT1000 input supports temperature measurement directly at the process. The passively air-cooled unit is designed for installation in a control cabinet.
Depending on the model, communication options include CAN, PROFINET, or EtherCAT. Multiple generators can be modularly networked for multi-channel applications.

Modular Heating System MHS – for multiple heating channels

The Modular Heating System (MHS) combines a controller with stackable generator modules. The controller can control up to seven modules via the module bus. Depending on the configuration, this allows multiple inductors and heating zones to be powered and regulated independently. Each module has 6 or 4 channels that can be used to individually control inductors as heating zones.

The MHS heating system is designed for applications with higher power and channel requirements. Integration into the machine control system is via a fieldbus. Existing variants and system specifications include a 400-V three-phase power supply as well as PROFINET, EtherCAT, and CANopen.

Food & Beverage applications

In professional vending machines and compact food applications, the heating generator SHS can heat tools or components as needed. Whether an application is suitable is determined based on the specific material, geometry, and temperature profile.

Rolls, Cylinders, and Material Webs

In the textile, printing, and paper processing industries, rolls and cylinders are often heated in a targeted manner. Kendrion customizes roll or surface inductors to match the geometry and process requirements. When multiple heating zones are required, the induction generator MHS enables a modular system design.

Packaging Machines and Sealing Processes

When sealing films or cups, stable temperature conditions at the sealing point are crucial. A carefully coordinated combination of generator, inductor, and temperature measurement can support reproducible process control. The small induction generator SHS is a suitable option for individual, compact heating zones; for multiple zones that require separate control, the MHS can serve as the appropriate system foundation.

From System Design to Integration: The Right Induction Heating System for Your Application

Every heating application has different requirements in terms of power, temperature control and integration. Efficient and reproducible heating therefore depends on the optimal interaction between the induction generator, inductor and application. Kendrion supports you from feasibility assessment and component selection to system design and integration into your machine.

Your benefits of a tailored system solution:

Targeted energy transfer: Heat is generated directly in the workpiece or tool, reducing unnecessary heating of the surrounding area.
Power matched to your needs: Whether the compact SHS or the modular MHS, Kendrion offers the right generator solution for different power and channel requirements.
Application-specific inductors: Geometry and energy transfer are tailored to the material, target temperature, cycle time and installation conditions.
Precise process control: Heating power can be adjusted to process requirements. Temperature measurement and control support reproducible results.
Easy machine integration: Power supply, sensors and fieldbus communication are taken into account during system design.
